"MANUAL-POWER lICE-C'UTTING MACHINE-1 SPECIFICATION forming part of Letters Patent No. 287,883, dated November 6, 1883.

Application inea March 21,1883. (No model.)

To all whom it `may concern: f

Be it known that we, ABRAHAM L. STAUF- FER and PHILIP STAUPFER, citizens of the United States, residing atStevens, county of Lancaster, State of Pennsylvania, have in-` vented aVr new and useful Improvement in Manual-Power vIce-cutting Machines, of which the following is a specification.

Our invention relates to ice-cutting machines operated by hand or manual power.

The obj ect of our improvement is to furnish a machine adapted to the purpose, simple in its construction and positive in its operation,` easily adjusted, guided, and operated. We attain the above results bythe mechanism illustrated in the accompanying drawings, forming part of this specification, in which similar parts are referred to by letters of similar character throughout. Y

Figure l is a perspective view of the machine upon the ice. Fig. 2 isa plan of the machine; Fig. 3, a -perspective'view of the gage for, regulating the width of ice-cake; Fig. 4, aplan and side elevation of the gage for depth of cut; Fig. 5, a front and side elevation of the handle-adjuster. Y

A represents the ice; A', the edge of a cut; B, the side frames of the machine; B', crossrails; B2, legs; C, casters; D, carrying and driving wheels; D', shaft for same; E, spurgear wheel; F, spur-pinion; F', shaft for same; F2, second spur-wheel; G, second pinion; G', saw-spindle; G2, saw; G, nut for securing same; H, gages for depth of eut; I, side gages for width of cake of ice to be cut; I', rods to same; I2, clamps for rods; J, handle-adjuster for height; K, handles; K', cross-bar; K2, pressure-bar; K3, pins for adjusting the handles; L, rope-eye.`

rllhe construction of themachine is as follows: We take hard wood for the sides and cross-rails, and, making the sides about three feet long, frame the first cross-railinto the same, two inches from the rear end, and with a space of thirteen inches between it and the center rail. The forward rail is capped on the top of the sides about fifteeninches from` the center rail. The carrying-axleis placed, about fifteen inches from Ithe rear, upon the 5o lower edgeV ofthe side picces,gB,'and has mounted upon it the two prodding drivingwheels D, and on the left side, between the wheel D and the-frame, a spur-wheel of about `twelve inches diameter, one-inch face and three-eighths-inch pitch. The prod-wheels are preferably made of wood, (or iron,) slightly larger in diameter than the gear-wheel, of

about two inches face, and the prods driven v(or screwed) iny staggering across the face. A counter-shaft, F', is mounted upon the top edges of the frame, has at its outer end a pinion, F, of about one-inch diameter, in gear with the wheel E, and at the opposite end, inside of the frame, a second gear-wheel, F2, of .the same diameter as the first. The saw-spindle G' is mounted below the frame,with apinion, G, in gear'with the wheel F2, andthe saw G2 central' to the frame, resting against a col` lar on the spindle, and secured in place intheusual manner by a screwed nut, G3. The gages for depth of cut H are of three inches by one fourth inch, wrought iron or steel, about eight inches long, havingV a slot in the center, and are secured to the outside forward ends of the frame by a bolt and nut. 'The handles K are formed of vone-and-three-fourths inch square hard wood, with a cross-handle, K2, for pushing or pulling, a cross-rail, K', for stiffness, are secured to the top of the framecap,at the vforward end,by a bolt in each passing upward through the sides B and cap-railA B'. On the rear lrail of the frame is placed an adjusting-fork, J, secured by bolts to thc rail,`the arms of the fork extending upward about ten inches, and perforated with four or more holes in each. The 'fork is` made of one-and-one-half inch by three-eighths-inch wrought-iron, and of such width over the arms as will make a snug t between the handles 'of the ice-cakes,we place in clamps l2 the rods I', upon the outer ends of vwhich we secure the bent pieces I, of one-eighth inch by one and three-fourths inch by one half inch. The clamps I2 have a bolt-hole, by which they are strung upon the same bolt that secures the forward end of the handles,and the nut,when

IOO

screwed, fastens all together. To adj ust the side gages the nut is slackened off and the rod I drawn out to the proper distance, the nut tightened, which clamps the rod and holds the gage I immovable. The cross-handle K2 projects beyond the rear ofthe frame about twentytwo inches.

The operation of the machine is as follows: Depressing the handle K2 to bring the casters in play, the machine is pushed or drawn to the point upon the ice from which the cut is to commence. The gages H arethen adjusted to permit the saw to eut to the desired depth, which will be governed by the thickness of the ice, about one-third of the thickness being all that is necessaryto give good wedging-surface to insure the cake following the cut in breaking away from the main body. The handles K are then adjusted in height to suit the operator, and the side gages, I, for regulating the width or distance between the cuts, and thereby the width of the ice-cake, are set and clamped, and the machine is ready. According to the depth of cut made, one or two persons will with ease push it forward. The prods catching in the ice compel the wheels D and yaxle D to turn, and with them the wheel E, which drives the counter-shaft F by pinion F, and wheel F`2,in gear with the pinion G on the sawspindle, drives the saw G2, which in this case is about seven inches diameter, the 'saw cut-v ting as it is advanced at the rate of about onefourth inch per revolution, and making alongitudinal eut of thirty-six inches to every revolution of the carrying-wheels D.

XVe do not confine ourselves to a manual operation of the described machine, as the parts may be proportionally enlarged, and horse-power used for operating the same.

To .ease and assist in operating the machine by manual power, an eye, L, attached to the central rail, may have a rope attached to the same, when any number of persons may assist in the ice-cutting. NVe place a box on the frame, which we load with sufficient weight to give the desired adhesion to the prods for working the several shafts, which are all supplied with bearings of the simplest form.

IVe are aware that we are not the first to produce a hand or manual-labor ice-cutting machine, but we believe our invention to be an improvement on all which have preceded it, and well adapted to performits duty as an icc-harvester.

Having shown the construction, operation, and advantages of our invention, we desire to secure by Letters Patent the following claim thereon:

In combination with a manual-power icecutting machine, the arrangement of gears E, F, F2, and G, with fixed wheels D on shaft D, counter-shaft F', saw-spindle G and saw G, and side gages clamped by clips I2, the whole arranged to be operated through the prodded wheels D, and force applied thereto through the handle K2, substantially as and for the purpose set forth.
